Fix broken Docker support (#2804)

* lsb-release package is getting deprecated

It is not present on Hirsute anymore so we better remove its dependency

* - remove lsb-release dependency from docker
- exit if Docker version is too low (check works only on Ubuntu builds, else doesn't do anything)

Reference: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1916485

* Cleanup

* Remove quotes for proper pkg install

* Automatically upgrade Docker engine

* Missing python dependencies

* Bugfix - debian name is not just one word

* Put this back

* provoke error

* Revert

* Adjust Github runner to make bionic and focal and compile u-boot for test

* Adjust cron

* Remove Bionic, cron back to 14 days

* Change to ubuntu-latest
